Abstract: A display apparatus including a foldable touch display panel and a display driving device is provided. The foldable touch display panel includes a plurality of touch sensors. The display driving device is coupled to the foldable touch display panel. The display driving device is configured to determine a folding angle of the foldable touch display panel according to a capacitance variation of the touch sensors in a folded state, and drive the foldable touch display panel to operate in a full panel display mode or in a partial panel display mode according to the folding angle.

Abstract: An electronic apparatus including a display panel and a driving circuit is provided. The display panel includes a plurality of display units. Each of the display units includes a light-emitting element. The driving circuit is coupled to the display panel. The driving circuit is configured to output a scan signal and a reset signal. When a reset interval of the scan signal is transmitted in a non-display area of the display panel, the driving circuit compensates the reset signal and outputs the compensated reset signal to reset the light-emitting element.

Abstract: A projection device includes a light source module, a display panel, a freeform-surface reflective mirror, and a projection lens. The light source module includes a light source, a first Fresnel lens element, and a second Fresnel lens element. The first Fresnel lens element and the second Fresnel lens element are parallel to each other and located between the light source and the display panel. The display panel is arranged between the light source module and the freeform-surface reflective mirror. The projection lens is configured to transmit an image beam out of the projection device, and a direction of an optical axis of the projection lens is different from a direction of a normal of the first Fresnel lens element.

Abstract: A first driver circuit is configured to cooperate with a second driver circuit to control a display panel, wherein the first driver circuit is configured to output display data to a first area of the display panel and the second driver circuit is configured to output display data to a second area of the display panel. A method used for the first driver circuit includes outputting at least one emission control signal to control the second area of the display panel when the second driver circuit is disabled.
